Help need for plasmid DNA purification.
I am purifying plasmid DNA using Promega miniprepa DNA Purification
System from Novablue cell transformated by Clontech pEGFP-N1
containing the inserts. Some strange things happened, I really got the
plasmid with inserts, but allways accompanied by a 580 bp DNA band
before and after digestion (RNase can't remove this band).
Since the plasmid DNA is to be used for transfection, I got to figure
out what it is.
Does anybody have experience about this?
